Title: Printing plates for intaglio printing and method of producing them
IPC: B41N1/06
Filed: 1969-12-12
Abstract: 1283239 Printing surfaces; etching DE LA RUE GIORI SA 12 Dec 1969 [12 Dec 1968 12 May 1969 14 Nov 1969] 60822/69 Headings B6C and B6J An intaglio printing plate 2, which may be of nickel, or of brass or steel, and has depressions 3, is provided with a coating of, e.g. copper in the depressions and a surface layer of ink-repellent metal such as chromium on the lands between the depressions 3. The depressions 3 are filled with a material 5 which is not receptive to chromium and chromium is plated either on to the copper on the lands or, after removal of the unprotected copper, directly on to the nickel plate. Then the filler is removed. The filler material may be a mixture of wax and inorganic material, and may be sintered before the chromium is applied. Suitable filler materials may include barium sulphate, alumina, or acrylic powder or polyvinyl chloride with polyurethane, and may be removed with trichloroethylene or with cyclohexanone and methyl ethyl ketone.
Patent GB-2000574-A (GB)
Title: Eccentric rotary valve
IPC: F16K1/24
Filed: 1978-06-27
Abstract: The two supports 31 for the plug 19 in an eccentric rotary valve are joined and rotatively coupled by a wing member 47. As the plug is rotated from its closed position on the cooperating seat 11 by the rotation of a shaft 39 fixed to one of the plug supports, the wing member lies in the fluid flowing through the valve. This fluid flow causes the wing member to exert a rotative force on the shaft in the direction to move the plug in its valve-opening direction. This force shifts the inherently unstable control region of a rotative force, which the fluid flow causes the plug to exert on the shaft, and thereby extends and widens the range of plug positions in which an external rotative force applied to the shaft, as by a valve actuator, can uniquely determine, and exert exclusive control over, the shaft and plug positions. <IMAGE>

The signal on line 70 may be used to inhibit supply of output signals from the device 16 to an external apparatus and to render operational an identical apparatus (not shown) which also includes two identical computing devices whose outputs are compared on a bit-by-bit basis. <IMAGE>
Patent GB-2024462-A (GB)
Title: Integrated Closed Loop Engine Control System
IPC: F02D41/14
Filed: 1979-04-17
Abstract: A closed loop engine control system in which: the fuel delivery and ignition timing functions of the engine are responsive to a measurement of the engine's instantaneous rotational velocity (1004). Signals indicative of the profile of each torque impulse imparted to the rotary output member of the engine from the burning of an air/fuel mixture in the engine's combustion chambers are generated and electrically analysed to detect perturbations caused by deviations of at least two different engine operational parameters from desired values. Feedback correction signals indicative of the magnitude of the detected perturbations are generated (1007, 1008, 1009) and used to correct the fuel delivery and ignition timing functions of an engine control means to minimize the differences between the actual values of the operating parameters and the desired values. The correction signals may be applied to the engine control means through a state variable matrix which provides for the control of at least one engine parameter as a function of at least two different correction signals. <IMAGE>

Patent GB-2022353-A (GB)
Title: Pyroulectric vidicon error correction
IPC: H04N5/33
Filed: 1979-04-23
Abstract: A signal processing method for eliminating fixed error sources in the video signal B1, Fig 1 in a pyroelectric vidicon consisting therein that the signal value S1, f1 in each point P1, P2 of the pyroelectric plate is added to foregoing signal values relating to the same point for forming an integrated or mean value B2 of a great number of signal values of that point. This mean value, if differing from zero, is an estimate of the error f1 in the respective point and is subtracted from the signal value S1 in the latest received video signal. A device, Fig 2, for carrying out the method forms a running mean value of the signal V for each picture point in a memory M, older foregoing values of the signal making a progressively smaller contribution to the mean value. A suitably scaled version of this running mean is subtracted from the incoming signal to provide a corrected vidicon output. <IMAGE>

Filed: 1979-08-03
Abstract: An air line lubricator has a cylinder (14) forming a lubricant reservoir, the cylinder (14) being closed at both ends and there being a pipe (12) passing axially through the cylinder. The pipe (12) forms an air flow path.

Title: Processing and apparatus for compacting molding material
IPC: B22C15/08
Filed: 1981-02-12
Abstract: In a method of compacting molding material a compressed gas is caused to pass through a plurality of supersonic nozzles (19) by abruptly opening valves (26) between a compression chamber (20) and the molding material container (2, 3). The nozzles are aligned perpendicularly to the surface of the molding material, and the gas is accelerated to supersonic speed so that the pressure energy of the gas is converted optimally into kinetic energy, permitting the gas to strike the surface of the moulding material (sand) at great speed, resulting in sudden compaction. The apparatus includes nozzle and valving mechanism for accomplishing the method. <IMAGE>

Title: Reservoir with liquid level sensing device
IPC: B60T17/22
Filed: 1981-06-03
Abstract: The reservoir has a liquid level sensing device incorporated in a cover 14,48 for the reservoir tank. The sensing device comprises a float 30 on which a magnet 32 is mounted for movement past a magnetically operable switch device 34. The float 30 is slidable on a hollow tubular portion 24 depending from the cover, and the switch device 34 is located within the tubular portion 24. The cover comprises two portions 14,48 of which the lower is in sealing engagement with the periphery of the reservoir and the upper portion 48 overlies the lower portion 14 to provide a complete weather shield over the lower portion. The cover portions 14 and 48 are connected by wall means which define a channel between them for housing lead wires from the magnetically actuable switch device. In this way the oil in the reservoir can be maintained pure by shielding it from ingress of moisture, and external parts around the reservoir can be protected from oil leakage from the reservoir. <IMAGE>
